Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528502, here are decompositions:

11 + 528491 = 528502
83 + 528419 = 528502
89 + 528413 = 528502
101 + 528401 = 528502
173 + 528329 = 528502
239 + 528263 = 528502
311 + 528191 = 528502
449 + 528053 = 528502

Showing the first eight; more decompositions exist.
